| 18 | Installing gzip
|
|---|
| 19 |
|
|---|
| 20 | Since there are many makefiles there are many possibilities
|
|---|
| 21 | compiling and installing gzip. For most of them, it is important,
|
|---|
| 22 | that you start them from the SOURCE-Directory (that is where
|
|---|
| 23 | gzip.c is), not from the [.vms]-directory. Otherwise the compiler
|
|---|
| 24 | won't find the source-files.
|
|---|
| 25 |
|
|---|
| 26 | Using gcc saves disk-space, but needs longer to compile
|
|---|
| 27 | VAXC gzip.exe 95/96 Blocks
|
|---|
| 28 | gcc2.3.3 gzip.exe 86/87 Blocks
|
|---|
| 29 |
|
|---|
| 30 | To install gzip one has to perform the following steps:
|
|---|
| 31 | 1. compile sources (*.c, [.vms]*.c)
|
|---|
| 32 | 2. link executable gzip.exe
|
|---|
| 33 | 3. Make entries gunzip.exe and zcat.exe to gzip.exe.
|
|---|
| 34 | These are similar to hardlinks in UNIX
|
|---|
| 35 | >>If You wish to do this by hand, see for example makegzip.com.<<
|
|---|
| 36 | The Entries can't be simply deleted, use 'set file /remove' .
|
|---|
| 37 |
|
|---|
| 38 | 4. Rename executables (*.exe) to Your prefered exe-directory. If it is on
|
|---|
| 39 | another Device, then you should only copy gzip.exe and do the
|
|---|
| 40 | entries gunzip.exe and zcat.exe by hand (3.).
|
|---|
| 41 |
|
|---|
| 42 | 5. Setting up Symbols for the executables:
|
|---|
| 43 | Place the following lines in Your login.com
|
|---|
| 44 | Change "disk:[directory]" as appropriate.
|
|---|
| 45 | $ gzip == "$disk:[directory]gzip.exe"
|
|---|
| 46 | $ gunzip == "$disk:[directory]gunzip.exe"
|
|---|
| 47 | $ zcat == "$disk:[directory]zcat.exe"
|
|---|
| 48 | 6. insert help-file gzip.hlp in any Help-library,
|
|---|
| 49 | for example in sys$help:helplib.
|
|---|
| 50 | this can be done by $lib sys$help:helplib/help gzip
|
|---|
| 51 | (I did not try this command)
|
|---|
| 52 |
|
|---|
| 53 | Steps (4.)5. through 6 must be done by hand.
|
|---|
| 54 | Steps 1 through 3(4.) may be done by one of the makefiles:
|
|---|
| 55 |
|
|---|
| 56 | a) MAKEGZIP.COM
|
|---|
| 57 | This was crated from MAKEFILE.VMS and later on edited. It uses the
|
|---|
| 58 | VAXC-Compiler and does compiling, linking and making the entries.
|
|---|
| 59 | Usage:
|
|---|
| 60 | - change to the Source-Directory
|
|---|
| 61 | - copy vms.c
|
|---|
| 62 | $copy [.vms]vms.c []
|
|---|
| 63 | - start compiling, linking, entries
|
|---|
| 64 | $@[.vms]makegzip
|
|---|
| 65 | if everything is OK. then you get gzip.exe, gunzip.exe, zcat.exe
|
|---|
| 66 | continue at Step 4.
|
|---|
| 67 |
|
|---|
| 68 | b) MAKEFILE.VMS
|
|---|
| 69 | Makefile for a vms-make utility (NOT gnu-make).
|
|---|
| 70 | Is uses the VAXC-Compiler and has the Advantage over MAKEGZIP.COM
|
|---|
| 71 | that make checks dependencies. This is helpfull if You have to
|
|---|
| 72 | recompile several times, for example after editing the sources.
|
|---|
| 73 | - change to the Source-Directory
|
|---|
| 74 | - copy vms.c
|
|---|
| 75 | $copy [.vms]vms.c []
|
|---|
| 76 | - start compiling, linking, entries
|
|---|
| 77 | $make /input=[.vms]makefile.vms
|
|---|
| 78 | if everything is OK. then you get gzip.exe, gunzip.exe, zcat.exe
|
|---|
| 79 | Continue at Step 4.
|
|---|
| 80 |
|
|---|
| 81 | c) MAKEFILE.GCC
|
|---|
| 82 | Same as MAKEFILE.VMS, but uses gcc
|
|---|
| 83 | - Use $make /input=[.vms]makefile.gcc instead of make ....
|
|---|
| 84 |
|
|---|
| 85 | d) MAKEFILE.MMS
|
|---|
| 86 | Makefile for the MMS-utility. Similar to MAKEFILE.VMS
|
|---|
| 87 | - Use $mms /description=[.vms]makefile.mms instead of make ....
|
|---|
